Objectives and Applications
|
The SCISAT satellite has been in continuous spaceflight operation since 2003. It now measures over sixty (60) atmospheric species at still one of the world’s highest vertical resolutions possible, and includes ozone, ozone depleting substances, all major greenhouse gases, and HFCs. Many of these species are measured by no other instrument or satellite world-wide, making Canada the sole provider of these datasets globally. As of 2024, the objectives of the mission remain to broadly assist in monitoring the UN Montreal Protocol, the Kigali Amendment, the Paris Climate Agreement, and the Canadian Environmental Protection Act. Specific objectives include to assess the quality of model predictions for: EC’s UV forecasting system, atmospheric carbon transport, and climate-chemistry process studies.

SciSat-1: ACE-FTS and MAESTRO
Jan-2003
| SciSat-1 is a CSA atmospheric science mission carrying the Atmospheric
Chemistry Experiment-Fourier Transform Spectrometer (ACE-FTS) instrument, which measure the vertical distribution of trace gases, and the Measurement of Aerosol Extinction in the Stratosphere
and Troposphere Retrieved by Occultation (MAESTRO) instrument, a dual-channel
optical spectrometer in the shortwave to thermal infrared range. Access is provided through the ESA TPM scheme. Read more
